Application filed December A. further object of the invention to so construct a corn razor that it ordinarily requires no manual adjustment but will automatically adjust itself to effect theparingoperation in a mosteihcient manner.

Corn razors asheretofore constructed invariably embody severalparts adaptedto be assembled and adjusted by the user and in practically every instance the cutting blades are rigidly clamped in position through the employment of variousclamping means. The present invention in contradistinction is formed entirely from .a

single blank of material stamped out into the desired configuration and thereafter bent into proper adjustment. The adjustment referred to is mechanically determined by the tools employed inthe manufacture of the implement and the ultimate purchaser and user is not required to assemble any parts or to vary its adjustment. The device is unusually simple in construction, yet highly eflicient in the carrylng outof its intended functions.

In its preferred practical form, it is. constructcd from a blank of sheet metal stamped up by suitable diesand of elongated shape. One and of the blank is-sha-r iiened to form a cutting edge and the blank is slotted transersclyinternicdiateits ends to form a clearance slot. Aftertheblanking operation is concluded and the cutting edge sharpened, the blank is manipulated by forming dies to bend substantially one longitudinal half of the blank into curved configuration, leaving the other portion of'the blank substantially straight whereby it is adapted to serve as a handle. The free end of the curved portion is returned upon itself so that the cutting edge is substantiallyjuxtaposed with the RAZQBI.

clearance slot from which it is spaced a short distance.

In practice, the mctalused is preferably more or less resilient so that the returned portion of the blankwhich carries the cutting edge, while adapted to normally maintain its fixed position, is capable of yield ingslightly in the event; thatthe cutting edge encounters a hard corn and as a result of this yielding action, the application of excessive force which would be apt to result in cutting of the foot when the corn was finally out through, is obviated and the device is rendered thoroughly safe in inexperienced hands.

specified, will lye-apparent from the following description and claims when read in conjunction with the accompanying drawings.

The accompanying drawings illustrate one practical embodiment of the invention, but the construction therein shown is to be understood as illustrative, only, and not as delining the limits of'the invention.

Figurel is a perspective view showing a corn razor embodying this invention.

Features of the invention, other than those shown in Figure 1.

Figure 3 is a rear elevation of the razor.

Figure a is a front view of the razor. Figure 5 is a section on the line 5-5 of Figure 3; and,

Figure 6 is a View of the blank from which the razor is formed.

In constructing a razor sliowninFigure 1 of the drawings, ablank such as shown in Figure 6 is first stamped from sheet metal. This blank maybe divided for the purpose of graphic illustration into three parts which are designated in Figure 6 as 1, 2 and 3. The part 1 is to constitute the handleportion, the part 2 the guard portion and the part 3 the blade portion. These portions may be of any suitable contour, particular shapcs being immaterial so far as the present invention is concerned.

The blank 1 is stamped out fiat and during the blanking operation, the guard portion 2 is transverselyslotted as shown at 4i to form a guide slot which as. shown in Fig ure 6 ispreferably of substantially thesame length as, the width of the blade portion 3, this blade portion 3 preferably being somewhat narrower than the guard portion 2.

the free end of the blade portion 3 is sharpened in any suitable manner'to provide a cutting edge 5 and at the conclusion of this operation, the blank is ready to be formed into finished shape. This is accomplished by means of suitable forming dies and in practice is eitected in two operations. That is to say, the handle portion 1 of the blank is left flat and constitutes the handle 1 of the implement. while the guard portion 2 is 'bent into substantially a half circle to form the semi circular guard 9, of the implement. The blade portion 3 is then bent back or returned over the exterior of the guard portion 2 to bring the cutting edge 5 in juxtaposition with the clearance slot, but nearer the further edge of said slot, so that between said further edge and the cutting edge. a relatively narrow space is left, as clearly appears from Figure 5. In bending back the blade portion 8, the curve of the bend is preferably swung on a relatively large arc, so as to not unduly crimp or free ture the metal and to furthermore provide a more or less resilient looped connection between the guard and the blade. The great er portion of the blade may if desired contact wi h the exterior face of the curved guard and. in practice, I. find that this is preferable since sr .ontacting relation be tween the parts maintains the cutting edge in very good adjustment relative to the juxtaposed edge of the clearance slot. The structure however is such that if the cutting edge strikes an unyielding corn. callous or other obstacle, the blade is adapted to give or yield slightly it excess pressure is applied. through the handle. W hen the oper ator feels the bladegive or yield, he will uiwonsciously relax the pressure and in so doing will he guarded against inadvertently forcing the blade through the obstacle with consequent quick acceleration of the blade after passage therethrough which is very apt to result in the cutting of the flesh. This constitutes one oil the foremost dangers from corn razors when in inexperienced hands and marks the cause of the greater portion of injury resulting through their use. I

The present construction entirely obviates the said danger of injury through the yield ing connection referred to.

The finished implement is shown best in Figures 1-3, from which it will be apparent that the guard portion, as well as the blade, present to the skin a smooth curvilinear sur face while the cutting edge of the blade is substantially tangential to this surface. This construction enables the razor to be readily guided during its operations and to slide easily over the skin. hiloreover', the said convexity enables the cutting edge to be presented at the inclination or angle with reference to said curved surfaces which is best adapted to secure the desired results in the use of the razor. The opposite ends of the cutting edge are rounded off as shown at 6, so as to eliminate sharp corners which would be apt to scratch or wound. In practice, I prefer to so proportion the width of the blade relative to the slot that the rounded portions referred to may rest upon the guide beyond the'opposite ends of the slot and thus accurately space the cutting edge from the contiguous edge of the slot for the purpose of obtaining more accurate adjustment. This engagement is however not mandatory but can be dispensed with without departing flOll'l this invention.

It'will be apparent from the foregoing detailed description that the implement of this invention is of unitary or one-piece construction and that the looping back of the blade from the forward edge of theguard is not only a highly'practical method of construction. but produces marked eiiiciency of the razor when in use. Resilient properties of the connection referred to are idle'whcn not tllNl lS lllllil'ltNVll in COI'Il I'RZOI'S 2S DOW COD- structed. The drawings show the invention in its pre terred form; but I wish it understood that slight changes in shape may be made without departing from the invention which is commensurate with the appended claims.

Having thus fully described the invention, what elaim'as new and desire to securel'iy liettersl atent is:

l. A. one-piece corn razor embodying a sheet metal blank. a portion intermediate the ends of which is longitudinally bent to form a guard which is provided with a transverse slot, one end portion of the blank serving as a handle a d the otherend portion of the blank being looped back over the outside of the curved guard and having a cutting edge juxtaposed with the slot and normally spaced from the edges of said slot by facial engagement of the blade with the guard.

2. A one-piece sheet metal corn razor embodying a substantially tl shaped guard pro vided at its base with a transverse slot, an integral. upstanding extension on one arm of the guard constituting a handle and an in tegra'l' blade turned back from the upper end of the other arm of the guard and longitudinally bent around the outer surface ot the guard and terminating in a sharp cut ting edge juxtaposed with the slot and main tained in proper adjustment lClZlilYC to said slot by facial engagen'ient between the blade and guard.

In testimony whereof I have signed the foregoing specification.
